### Colors

If you'd like to customize your values for kind of colors, use the `theme.colors` section of your theme.

```diffjs
  // theme.js
  import { th, generateHexAlphaVariants } from '@xstyled/styled-components'

  export const theme = {
    colors: generateHexAlphaVariants({
      // ...
+     'deep-blue': '#00008b',
+     'primary': th.color('red-600'),
    }),
  }
```
